Abstract: ABSTRACT OF THE DISCLOSURE            A joining device for use in joining floating elements such as pontoons or the like to form buoying structures, e.g. platforms, bridges, etc.  The device comprises elements defining two channel members and a key of "I"-shaped cross-section.  The channel members define a slot receiving the web of the "I"-shaped key with the flanges thereof located in the respective channels, the flanges preventing separation of the channel members from each other.  Two inclined plates at the base of the key engage two trapezoidal half-wedges to clamp the channel members together against opposite sides of a fastening plate located between the channels and connected to one end of the key.  The device is relatively simple and is suitable in use of joining together lateral edges of adjacent pontoons.

Abstract: S P E C I F I C A T I O N                      TIER COUNTER MEANS RESPONSIVE TO TIER PATTERN STORAGE CAM POSITION       ABSTRACT OF THE DISCLOSURE         Tier pattern selection on the disclosed bale wagon involves periodic rotation of a memory element in the form of a cam plate relative to a cam follower which is connected to means on the bale wagon which will cause the tier pattern selected to be formed.  The cam plate is rotated through successive predetermined displacements to successively bring respective peripheral lobes on the cam plate into engagement with the cam follower in a desired sequence.  Accurate rotation of the cam plate is facilitated by an electric motor drivingly interconnected to a sprocket mounted on the cam plate shaft, a series of switches and circuitry which interconnects the motor with an electrical power source on the bale wagon. Closing and opening of the circuitry is controlled during normal operation of the bale wagon by certain of the switches so as to cause rotation of the cam plate after each tier selected has been formed and delivered to the load bed of the bale wagon until the cam follower becomes disposed at the next successive position along the cam plate lobes.  The improvement relates to a tier counter incorporated in the circuitry and operable to advance one count and register the number of tiers thus far formed on the bale wagon each time the cam follower become disposed at the next position.
